Powerful instrument for tuning forks and Akiyama probes
Mad City Labs MadPLL®
MadPLL® is a powerful instrument package that allows the user to create an inexpensive, high resolution resonant scanning probe microscope using Mad City Labs nanopositioning systems. In short, MadPLL® can be used to create an 'instant' closed loop AFM or NSOM at a fraction of the cost of commercial systems. MadPLL® is suitable for nanoscale characterisation and nanoscale fabrication applications such as optical antennas, nano-optics, semiconductors, data storage, and more.
MadPLL® has been specifically designed for resonant probes such as tuning forks and Akiyama probes. In addition, MadPLL® is fully compatible with high resolution nanopositioning systems from Mad City Labs, which makes it easy for users to build a scanning probe microscope with a flexibility that cannot be achieved with other commercial systems.
"The seamless integration of hardware combined with the built-in automated control of MadPLL® means that you can concentrate on getting results, not tweaking parameters."
MadPLL® is ideal for research and teaching laboratories offering high performance, versatility, simplicity and excellent value for money.
Akiyama Probe or Tuning Fork
MadPLL® is an integrated solution that includes the digital phase lock loop (PLL) controller - containing a digitally controlled proportional integral (PI) loop , software, sensor amplifier board and resonant probe mounting board. Simply add your Akiyama probe or tuning fork to the probe board to create a powerful force sensor for scanning probe measurements.
The PLL controller has three operational modes: self oscillation, PLL driven, and (lock-in) DDS driven. The probe can be controlled in constant excitation or constant signal mode. Measured outputs from the controller include changes in frequency, amplitude or phase shift.
The sensor amplifier and probe board assemblies are compact and can be fitted to existing instrumentation. The probe board simply plugs into the sensor amplifier board. The sensor amplifier board can be mounted to a precision positioner such as a closed loop nanopositioning system.
Scanning probe microscope
MadPLL® simplifies the control of your scanning probe microscope. Many of the functions of MadPLL® are fully automated - no front panel knobs or pots to adjust! The flexible and user friendly MadPLL® software allows complete control of user adjustable parameters. Among the software features are automated setup, configuration control, auto Q calculation and automatic parasitic capacitance compensation (PCC) control. These included features are designed to simplify setup and accelerate the data acquisition process.
